SOIL-PULVERIZER.

Application filed December 18, 1919.

T 0 all whom it may concern:

Be it known that I, HENRY F. Ronnarnyna, a citizen of the United States, and a resident of Sterling, in the county of lVhiteside and State of Illinois, have invented certain new and useful Improvements in Soil-Pulverizers, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The present invention has relation more particularly to that class of soil pulverizers in which front and rear rollers are employed for breaking up the soil, although features of the invention are applicable to soil pulverizers in which a single roller is used.

The invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of the specification.

Figure l is a view in side elevation of a pulverizer embodying my invention. Fig. 2 is a plan view. Fig. 3 is a view in vertical section on line 3-3 of Fig. 2. Fig. 4: is a de tail view in vertical section on line l& of Fig. 2. Fig. 5 is a detail View in vertical section on line 55 of Fig. 2. Fig. 6 is a de tail view in vertical section on line 66 of Fig. 2. Fig. 7 is a detail view in. vertical section on the line 7-7 of Fig. 2.

The main frame of my improved pulverizer comprises the end frames or castings A that are connected together by the longitudinal bars 13. These bars B are preferably formed as angle bars and their ends are bolted to the end frames A by bolts Z2 passed through flanges a (see Fig. 3) formed upon the inner side of the end frames A. Across the tops of the longitudinal bars B extends a stub tongue that is preferably formed of a pair of angle bars C arranged to form a channel to receive the tongue or pole D. The tongue or pole D is secured to the stub tongue by bolts (Z and d that pass through the tongue and through the angle bars C. As shown, the angle bars C are arranged at a slight distance from each other, forming a space between the lower inturned members of the angle bars (see Figs. 2 and 7) and through this space will extend the clevis bolts E and e that pass vertically through the tongue D. Diagonally across the lonitudinal bars B extend the brace bars F t at are bolted to the bars 13 as at f, and the Specification of Letters Patent.

Patented Aug. 2, 1921. Serial No. 345,756.

front ends of the'brace bars F are given a quarter turn to form the portions 7 through which pass one of the bolts d that unites the pole or tongue D to the bars C.

Upon the top of the angle bars C adjacent its rear end is mounted an adjustable plate or casting G(see Figs. 2 and 7) that is preferably formed with depending ribs 9 to fit between the upper edges of the angle bars 0.

To this plate or casting G is connected, by

the bolts H and H, the lower end of a seat support K, the seat support being preferably formed of a resilient metal bar bent as shown and carrying at its upper end a drivers seat Z2. The bolts H and H enable the drivers seat to be adjusted forwardly andbackwarclly on the stub tongue, for a purpose to be presently stated. As shown in Fig. 6, the rear longitudinal bar B has its upper member formed with a series of holes 6 through any one of which the bolt H may be passed, and the lower end of the bolt H passes through a plate It that extends across the space between the inturned members of the angle bars C. WVhen it is desired to adjust the drivers seat forwardly or back- 'wardly, this can be readily done by withdrawing the bolt H and loosening the bolt H so as to permit the plate G to be shifted forwardly or backwardly and *hen the plate G is in the desired position, the bolt H will be passed through the proper hole 6 in the bar B and through the plate G and support K and the bolts H, H will then be tightened. If it is desired to adjust the drivers seat to an extreme forward position, a plate corresponding to the plate it can be used for the lower end of the bolt H, and the bolt H can then be passed through one of the holes 6 of the bar 13, or through a plate like 72..

To the bottoms of the end'frames A are bolted, as at m, the journal bearings m of the axle M of the front roller M. As shown, this roller M is formed of a plurality of disks or pulverizer wheels, each having its periphery shaped toform a central cutting portion. As this construction of roller is well known to those familiar with thisclass of devices, its details need not be more fully described.

The several disks or wheels comprising the roller M are held snugly together upon the axle M by'means of the end collars m that are secured by set screws to the axle M. j cent he inner face of each of the journal bearings m and secured by a set screw to the axle M is a collar M and upon the outside of each journal bearing m, and held in place by a cotter pin m is a collar M these collars M and M serving to hold the axle M in proper relation to the bear ing m. V

To the lower rear portion of each of the end frames or castings A is pivotally connected, as by a bolt 29, a bar P preferably of angle shape and extending rearwardly from the main frame, and each of these bars P has bolted to and depending from its rear end the journal bearing P in which is mounted the axle R of the rear roller R. The bolts' that connect the journal bearings P to the bars P pass through the lower outwardly projecting members of the angle bars P. The roller R is similar to the roller M, being f0 "med of a series of disks mounted upon the axle R, and the axle R is provided with collars r, r and?" which serve to hold the disks in place upon the axle and the axle in proper relation with respect to the journal bearings P. By thus mounting the rear roller B, it can rise'and fall with any irregularities of the ground.

In order to exert upon the rear roller R a pressure sufficient to enable the disks of the roller to properly act upon the soil, 1 have provided the adjustable compression springs S that are preferably mounted on the pivot bars P, in the manner next to be described. As shown, the springs S are carried by the vertically disposed rods Each of these rods S is provided at its lower end with a T-shaped head 8 through which passes the pivot bolt 8. Each of the bolts 8' 'passes through the corresponding bar P and through a bar P the front end of which is bolted, as at p, to the lower portion of the corresponding end frame A. The rear portion of each bar P (see Fig. 2) is bent and its rear end is connected, as by bolts 79, to the rear end of the corresponding bar P. The upper portion of each rod S passes loosely through a hole in the ad justing bar T that bears upon of the coil spring S (see Figs. 1, 3 and 5) The forward portion of the bar T is bent as shown in Figs. 1 and 3 and is connected by a stud or bolt t to the upper portion of the end frame A, the hole in the forward end of the bar T being sulliciently larger than the stud or bolt '6 to permit the verticalmovement of the bar. Through a hole the upper end in the bar T also passes the adjusting belt or screw lV, the lower end of which passes through the flange a of the end frame A and upon the threaded upper end of the screw W is arranged a threaded nut W having a hand lever w connected thereto,

. to permit the nut to be conveniently turned.

From the foregoing description it will be seen that when it is desired to increase the tension of the springs 53 and the pressure exerted by said springs upon the rear roller R, this can be readily effected by turning the hand lever to and thus forcing downward the adjusting bar T.

By varying the position of the support for the drivers seat in the manner above described, the weight of the driver can be shifted forwardly or backwardly so as to better balance the machine and modify the pressure upon the rear roller. When it is desired to use the pulverizer without the rear roller R, this can be readily accom plished by detaching the rear roller from the pivot bars that sustain it and the spring mechanism above described.

WVhile I have described what I regard as the preferred embodiment of my invention, it will be understood that the precise details of construction above set out may be varied without departing from the-spirit of their.- vention and that features of the invention may be employed without its adoption as an entirety. 1

Having thus described my invention,what I claim as new and desire to secure by Letters Patent is 1. A soil pulv'erizer comprising a main frame, front and rear pulverizer rollers, pivoted, vertically movable bars carrying at their rear ends the journals of the rear roller, springs for exerting'pressure upon the rear roller, and means adj acent to the seat for adjusting said springs.

2. A soil pulverizer comprising a main frame, front and rear pulverizer rollers, vertically movable bars pivoted to said main frame and carrying at their ends the journals ofthe rear roller, rods extending upwardly from said'bars, springs mounted upon said rods, verticallymovable adjusting bars connected at their inner ends to the main frame and having their outer ends arranged to compress said springs. and means adjacent to the inner ends of said bars for adjusting said bars.
